Or to make it a musical question: In The Hunger Games: Mockingjay, Part 1, the box-office-topping third film adaptation from Suzanne Collins' novels, whose dulcet tones move the masses more? Is it the singing of the expert-archer celluloid heroine, played by Jennifer Lawrence, or the 18-year-old New Zealand pop star, whose real name is Ella Yelich-O'Connor?

If you answered the latter - as well you might, since the über-teen Kiwi is the force behind the movie's soundtrack, which also features Kanye West, Ariana Grande, Miguel, Major Lazer, Chemical Brothers, Sia, and more - you'd be wrong.
